verse in the female. Elytra developed, parallel-sided, with the 

 apex rounded. Wings a little shorter than the elytra, hyaline or 

 coloured. Hind femora short and broad, scarcely incrassate ; the 

 upjier carina feebly denticulate; the lower carina regularly convex. 

 Hind tibiae straight. 



cj. The last tergite slightly widened on its sides, shallowly rotun- 

 dato-emarginate on the upperside, with the hind margin somewhat 

 incrassate. Supra-anal plate about as long as broad, with the 

 sides widely rounded and with a short median projection behind; 

 the median sulcus scarcely perceptible in the basal jjart only; no 

 distinct chitinous tubercles, or only a pair of very small ones. 

 Cerci almost horizontal ; the basal part thick and broad ; the apical 

 part thin, gradually recurved ; the aj^ex obtuse or pointed. Sub- 

 genital plate obtusely conical. 



$. Subgenital plate with an obtusangular projection behind, and 

 two shallow angular emarginations sideways from the projection ; 

 its surface feebly convex. Lower valves of the ovipositor, with 

 the apical parts short, broad, obtuse, not dentate basally. 



Genotype : CalUptamulus sulfurescens, sp. n. 



This peculiar genus seems to be represented in South 

 Africa by many species, since not less than three distinct 

 new species may be recognised amongst quite a small lot 

 of specimens now before me. The species are very close 

 to each other, but still there are quite good characters 

 which enables us to separate them without any difficulty. 



1. Calliptamulus sulfurescens, sp. n. 

 (Plate I, fig. 20.) 



^. Frontal ridge feebly impressed near the ocellum, above it 

 flat but with the margins somewhat raised. Fastigium of the 

 vertex at the apex oj^en, forming a widely rounded angle with the 

 frontal ridge. Lateral keels of pronotum very distinct, but obtuse, 

 almost straight, scarcely divergent backwards, reaching the hind 

 margin ; hind angle straight, not rounded. Mesosternal interspace 

 slightly transverse. Elytra extending a little beyond the apex of 

 the abdomen, but not reaching the hind knees. Supra-anal plate 

 with two very minute, scarcely perceptible chitinous points before 

 the middle. Cerci with the basal part a little longer than high; 

 the apical part somewhat longer than the basal ; the lower margin 

 in the apical third obtusangulate ; the upper margin of the apical 

 part feebly and regularly concave ; apex obtuse. 



General coloration brownish- ochraceous, with brown markings.
